Description

The method that noble metal is reclaimed from long-chain hydro carbons, tar, oils
The present invention relates to the method that noble metal is reclaimed from long-chain hydro carbons, tar or oils.
Catalyst has played important function in the various production processes in chemical industry.Many catalyst, which have, is used for it The noble metal in activated centre.The catalyst existed as heterogeneous catalyst can be removed from reactant mixture after the reaction, if It can reprocess and reuse if being applicable.
In homogeneous catalytic reaction, catalyst and product are present in same phase.This is made it more difficult to from reactant mixture In isolate catalyst.Under these conditions and due to the steady rise of noble metal price, recovery catalyst is particularly it and included Noble metal be valuable.
A kind of important industrial process of use homogeneous catalyst is the production of acetic anhydride.Annual about 1,000,000 tons of production should Product.Mainly rhodium and iridium complex is used as catalyst.Accordingly, it would be desirable to which substantial amounts of noble metal is used for the production of the catalyst.
In order to reclaim noble metal, required reaction product, such as acetic anhydride are removed from reactant mixture in the first step.So Residue is thickened to reduce total amount by evaporating afterwards.Thus obtained catalyst bottom sediment is the noble metal for including the catalyst Long-chain hydro carbons, oils or tar.
Distinct methods known in the state of the art from different Product recycling noble metals.Therefore, DE3223501C1, which is described, borrows The method for helping tellurium major precipitation rhodium from liquid organic residue.It is organic mixture to separate remaining after the noble metal, and it is needed It is disposed.
The known organic component for directly burning the residue containing noble metal from DE3134733C2 and WO99/37823A1. In such heat reprocessing, pending material generally in heating furnace laser heating to about 800 DEG C~1200 DEG C of temperature Degree, this depends on pending material.This process is referred to as ashing.Then, ash content of the gained containing noble metal is passed through into wet method Mode is reprocessed.
If making the catalyst bottom sediment by evaporating thickening, the i.e. tar containing noble metal, for example, given birth to from acetic anhydride The material of production, thermally treated, the heating of the material is accompanied by the generation of a large amount of foams.For example, heating half liter of Jiao in heating furnace Oil causes to produce up to 200 liters of foam.
Due to this extreme volume increase, it is economically according to the heat treatment for being ashed this kind of catalyst bottom sediment It is infeasible.Only have micro tar to be ashed in any given time.Energy requirement and time demand are all very big.
Undesirable foam generation is also a problem in other industrial process.In these areas, it has been proposed that disappear Infusion, is based particularly on those of silicone oil.
If silicone oil be added in the tar containing noble metal, then they are heated, then not only tar, also silicone oil Also it can be decomposed in heat treatment process.Foam can not be prevented.In addition after the completion of being heat-treated, find the silicone oil of residual in ashing It is present in afterwards with Impure forms in the ash content containing noble metal.This clearly increases the subsequent wet chemistry for reclaiming noble metal again Handle the time being related to and expense.
It is therefore an object of the present invention to the method for reclaiming noble metal from long-chain hydro carbons, tar or oils is provided, its In at least largely prevent foam generation.Defoamer must be still activity being up to about at a temperature of 1200 DEG C. In addition, the defoamer will not make the wet chemistry reprocessing generally carried out after heat reprocessing more complicated.
The purpose of the present invention is met by the method for the heat reprocessing for the tar containing noble metal, this method bag Include the heat treatment process in the presence of the defoamer of the ash content fraction with 0.1wt% or higher.It is included in the presence of wood chip The hot Retreatment method for the tar containing noble metal of heat treatment process is another theme of the present invention.
Within the scope of this invention, tar is understood as long-chain hydro carbons, oils, highly viscous liquid or tar.These are excellent Choosing is the bottom sediment of the homogeneous catalyst such as produced by evaporation thickening, from chemical process from acetic anhydride.Therefore, should Tar can be liquid or solid when heat treatment process just starts.
The tar is mixed with defoamer first, and heat treatment process is then subjected to again.The heat treatment process is in heating furnace Carry out, carried out preferably in batch-type furnace.The temperature of paramount about 1200 DEG C of the tar heating containing noble metal of defoamer is provided with, it is excellent Paramount about 1000 DEG C are selected, particularly preferably paramount about 800 DEG C.Heating furnace herein can be heated directly or indirectly.According to existing skill All types of heating are all feasible known to art.In addition to gas heating and oil heating, this also includes such as electrical heating.
Heat treatment in heating furnace also can comparably be carried out under inertia or oxidizing condition.It should not seek survival in protectiveness gas Body.Although this does not disturb the process.This is equally applicable to air and the oxygen included in it.
The heat treatment produces the ash content containing noble metal.Then the ash content reprocesses to reclaim Jiao by wet chemistry mode Contained noble metal in oil.Correlation technique is described later in detail in the prior art.
Therefore, the heat reprocessing in the scope of the invention includes heat treatment process and obtained in the heat treatment process containing your gold The subsequent wet chemistry reprocessing of the ash content of category.
The inventive method suitable for reclaiming all noble metals, i.e. gold, silver and platinum group metal from tar, rhodium, ruthenium, palladium, osmium, Iridium and platinum.Preferably, the tar includes rhodium and iridium, particularly preferably comprising rhodium.
Preferably, the defoamer in the scope of the invention is solid.In heat treatment process, the heating of tar is accompanied by foam Generation.Bubble according to produced by ensuring defoamer of the present invention bursts in the very early stage of formation of foam.Only form Very small bubble.This causes the tar volume in heat treatment process to increase negligible.
Defoamer and the pending tar containing noble metal are mixed with each other first, heat treatment process is then subjected to.Not only Tar ingredients, and the defoamer also burning in heat treatment process.Resulting ash content is dwelt on the first appearance in tar bubble In on its surface and/or outer membrane.Then, the defoamer ash content produced in heat treatment process ensures that the tar bubble produced is firm at its Burst after just occurring.
It is required that at least 0.1wt% ash content fraction, to ensure to produce enough ash contents.The ash content fraction or content of ashes are given The amount of combustion residue is determined.Ash content fraction is provided in units of the percentage by weight relative to defoamer dry.
If the ash content fraction is less than 0.1wt%, enough defoaming effects are cannot ensure.Equally, the volume of tar increases Plus cause the operation of the inventive method to become uneconomical.
0.5wt% to 0.8 wt% ash content fraction is preferably comprised according to defoamer of the present invention.
Ash content fraction is higher, and impurity present in the ash content containing noble metal is more.Reprocessed which increase wet chemistry Workload in journey.Ash content fraction in the range of 0.5wt% to 0.8wt% ensure that ash amount enough, while ensure that needs The impurity to be removed in the wet chemistry reprocessing process of the ash content containing noble metal reclaimed for noble metal is seldom.
Preferably, the tar containing noble metal relative to 100wt%, the defoamer fraction added is for 10wt% or more Height, particularly 10wt% are to 40wt%.
The tar containing noble metal relative to 100wt%, is realized using 10wt% weight fraction in heat treatment process Almost complete froth breaking.40wt% fraction is utilized more than so that the inventive method is uneconomical.Due to the size of heating furnace, at it The middle inside heating furnace combustion space for carrying out heat treatment process is predetermined, it means that it is limited.If described Combustion space significant portion is occupied by defoamer, then less space can be used for tar to be processed.Furthermore, it is necessary to a greater amount of Defoamer.Combustion space available for tar is smaller and amount of defoamer is bigger, then causes higher cost thus cause not Economic method.
Preferably, the defoamer has loose structure.Due to the loose structure, the tar containing noble metal can enter this The inside of defoamer.In this case, when methods described starts, independent mixture foam killer and tar be just before the heat treatment It is enough.Defoamer will not be separated.Therefore, good mixing is also ensure that in heat treatment process.In this case, at heat The defoamer ash content occurred during reason is uniformly distributed relative to the tar bubble occurred.This allows required froth breaking dosage to protect Hold in reduced levels.
It has proven convenient that being uniformly distributed due to defoamer ash content, it is appeared on each tar bubble.Unexpectedly, Confirm that even seldom ash bits on small tar bubble can also make the bubble eruption.
If directly mixing ash content and tar and gained mixture is subjected to heat treatment process, in heat treatment process also The mixture must be stirred, to maintain to be uniformly distributed.Tar is often highly viscous or almost solid before heat treatment. It is difficult or impossible to obtain being uniformly distributed for ash content in such highly viscous tar.Tar is changed into liquid when being heat-treated and starting State.Only after this point, i.e., in heat treatment process, it can just be evenly distributed.This turns into capital equipment demand must Palpus.Related mixing arrangement needs to keep stable under heat treatment temperature, that is, is up to about 1200 DEG C of temperature.
Low sticky tar can be well mixed before the heat treatment.However, this is separated again along with tar with added ash content And the risk of added ash-deposition, such as particularly when being heat-treated beginning.This needs also exist for the mixing in heat treatment process. Furthermore, it is necessary to add significantly larger amounts of ash content to ensure that the ash content is appeared on each tar bubble.This causes wet chemistry More impurity in reprocessing process, so as to increase cost.
Furthermore, it is necessary to produce the ash content in a separate process first.This means extra energy cost and it is a large amount of when Between demand.
For example, one or more natural materials can be used as defoamer.Natural materials in the scope of the invention are natures Present in renewable raw materials.The natural materials can be treated for the inventive method.It is possible to disappear according to the present invention Infusion is, the straw of such as wood chip, the paper containing additive, string such as hemp, flax or chopping, cereal for example wheat, rye, The shell of rice etc., and plant origin similar product.
Pure extraction cellulose can not be used, because it, which burns, does not stay residue.
Natural materials can be used in itself.However, with reference to different natural materials and being used in combination in the methods of the invention They are also feasible as defoamer.Their relative quantification ratio is herein defined as inessential.
Another embodiment of the present invention be directed to use with one or more natural materials the tar containing noble metal heat again Defoamer is used as in processing.Natural materials given above are used as froth breaking in the heat reprocessing of the tar containing noble metal Agent, the tar generally comprises 300 ~ 5000ppm bullion content.The natural materials are particularly suitable for again locating in the heat of rhodium-containing tar As defoamer in reason, the tar has 300 ~ 5000 ppm rhodium content.
The natural materials for being decreased to fritter are preferably used as defoamer, the length of its most major axis is 5mm or smaller, preferably For 3mm or smaller, particularly preferably 2mm or smaller.The geometry of defoamer herein is inessential, but most major axis Length given above is not to be exceeded.If the defoamer is smaller, distribution of the natural materials in tar to be reprocessed is more It is good.
For example, wood chip may be used as defoamer.It is preferred that the wood chip is dry wood chip.Wood chip is porous defoamer, and tar can enter Enter wherein.The moisture of wood chip reduces the absorptive capacity of tar, and decrement is equivalent to moisture.Therefore, wet wood chip is compared to dry Wood chip effect is reduced, and the distribution reached in tar is more uneven compared with the situation of dry wood chip.Wood chip can be come from The waste product of sawmill.The particular type of timber herein is inessential.
